Snell's Law describes light refraction at interfaces between different media. The ratio of sines of angles equals the ratio of refractive indices, explaining light bending.
Formel
n₁ × sin(θ₁) = n₂ × sin(θ₂)
Trinn-for-trinn guide
- 1Enter refractive indices of both media
- 2Enter incident angle θ₁
- 3Solve for refracted angle θ₂ using Snell's law
Løste eksempler
Inndata
n₁ = 1 (air), n₂ = 1.5 (glass), θ₁ = 45°
Resultat
θ₂ ≈ 28.1°
Light bends toward normal entering denser medium
Vanlige feil å unngå
- ✕Using degrees instead of radians in calculation
